In use the plates 6 are formed of different areas or with central openings of different sizes, in order to form bases for different sizes of commercial switches and the.

holes 20 are spaced apart so that one of such pairs of holes is in position to receive the attaching screws of a switch of a certa n make, so that the supporting means is adapted to receive the attachingscrews of switches of standard sizes and makes. The plate 6 is adjustable about-its axis in order to so position the switch that the sight opening thereof may be arranged so as to be conveniently read, the sight openings in the various makes of switches occupying differ- 'ent positions relative to the attaching screws as will be understood by those skilled in the art.

'What we claim is:

1. In combination, a conduit outlet box having a circular opening in one wall thereof and a notch leading from said opening, an electrical appliance for connection to wires in the box, and means for attaching the appliances to the box comprising a member engaging the outer surfaces of the wall of the box adjacent said opening and provided with a passage in alinement with said opening, a second member for engaging the inner face of the wall ofv the box adjacent the opening therein and having a length greater than the diameter of said opening, the second member being movable into and out of the box through said openings in the wall thereof when its longer axis is in registration with a diameter of said. opening intersecting the notch, and nonremovable from the box when its longer axis is out of registration with the lastnamed diameter, one of said members being movable toward and from the other and means for moving one of said members relatively to the other and-clamping said members against the coacting faces of the wall of the box, substantially as and for the purpose described.

2. In an electrical appliance and in combination, aconduit outlet box having a circular opening through one Wall thereof and a notch in said wall leading from the opening, a sheet metal ring resting against the outer face of said wall and overhanging the edge of the opening, a one piece sheet metal strip carried by said ring and of greater length than the diameter of the opening and non-removable through the same when its longer axis is out of registration with a diameter of the opening intersecting the notch, an electrical device seating on said ring, and means for retaining the device in place and for clamping the ring and strip against outer and inner faces, respectively, of the wall of the box, substantially as and for the purpose specified.

3. In an electrical appliance and in combination, a supporting and connecting de vice comprising a member in the form of a fiat ring provided with laterally extending lugs having openings ,therethrough, and a second member in the form of a fiat strip extending through the openings in the lugs and provided with a plurality of sets of openings, said opening being exposed through the opening in the first-named member, substantially as and for the purpose set forth.

4. The combination with a conduit outlet box having a circular opening, the margin of the wall around said opening being formed with 'a notch, and means for supporting an electrical appliance connected to wires in the box, said means comprising an annular plate engaging the outer surface of the margin of the wall around the opening, means for engaging the inner surface of the margin, the last-mentioned means comprising an offset tongue movable through the notch beyond the inner face of said margin and a tongue projecting from the inner edge of the annular plate and baclnvardly toward the outer margin of said plate, the end of the last-mentioned tongue engaging the edge of said margin of the wall around the opening, and the plate being mo able about its axis moving the firstmentioned tongue out of alinement with the notch, and means for clamping the means engaging the inner surface of said margin toward the plate substantially as arid for the purpose described.

The combination with a conduit outlet box having an opening; of means for supporting an electrical appliance connected to wires in the box, said means comprising a plate engaging the outer face of the margin of the wall around said opening, and having a central opening and lugs extending at an angle to the plate and being formed with slots, and a bridge'extending across the opening and having its end portions extending through the slots, substantially as and a central opening, and lugs extending at a right angle to the plate and being formed with slots, and a bridge extending across the opening and having its ends extending through the slots, and one of the lugs having a flexible portion forming one of the walls of the slot in such lug, substantially as and for the purpose described.

7. The combination with a conduit outlet box having an opening; of means for sup porting an electrical appliance connected to wires in the box, said means comprising a pla e engaging the outer face of the margin of the wall around said opening, and having a central opening, and lugs extending at a right angle to the plate and being formed with slots, and a bridge extending across the opening and having its ends extending through the slots, and shoulders for engaging opposing faces of the lugs, and one of the lugs having a flexible wall at one end of the slot thereimsubstantially as and for the purpose specified.

8. The combination with a conduit outlet .bo-x having an opening in one wall thereof; of. supporting means comprising parts for engaging inner and outer surfaces of the -margin of the wall around said opening,

one part being movable toward and from the other, and an electrical appliance mounted on the outer part and having an attaching screw threading into the inner part of the supporting means and serving to clamp the parts of the supporting means to the margin of said wall, substantially as and for the purpose specified.

9. The combination with a conduit outlet box having an opening in one wall thereof, the margin of the wall around said opening being formed with a notch; of supporting means comprising parts for engaging the inner and outer surfaces of said margin, the part engaging the inner margin being formed with a tongue movable through the notch and out of alinement with the notch into engagement with the inner face of the margin of said wall, and'zan electrical appliance supported by said means and including an attaching screw threading into the part engaging the inner surface of said margin and serving to clamp the parts of the supporting means on the margin of said wall, substantially as and for the purpose set forth.

10. The combination with a conduit outlet box having a circular opening in one wall thereof; of supporting means comprising an annular plate engaging the outer face of the margin of said wall and a bridge detachable from the plate and extending diametricallythereof and having tongues at its opposite ends for engaging the inner surface of the margin of said wall, and an electrical appliance mounted on the plate and hat .ng an attaching screw threading into the bridge and serving to clamp the plate and bridge on the margin of said wall, substantially as and for the purpose described.

11. The combination with a conduit outlet box having a circula' opening, the margin of the wall around said opening being' formed with a notch; of supporting means comprising an annular plate engaging the outer surface of the margin of the wall around the opening, the plate being formed with diametrically disposed lugs extending at an angle thereto through the opening and formed with slots, and a bridge having its ends extending through the slots, the bridge having tongues at its ends for engaging the inner surface of the margin of said wall, one of the tongues being movable through the notch beyond the inner face of the margin of the wall around said opening, and the plate being movable about its axis for mov ing said tongue out of alinement with the notch, and an electrical appliance mounted on the plate and having an attaching screw threading into the brid e, substantially as and for the purpose set orth.

In testimony whereof, we have hereunto signed our names in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 6th day of December 1910.
